Specification of Letters Patent.

Patented May 19, 1908.

Continuation of application Serial No. 362,158, filed March 13, 1907.This application filed June 26, 1907. Serial To all whom it may concern:

Be it known that I, JOHN C. ORowsoN, a citizen of the United States,residing at Bagdad, in the county of Santa Rosa, State of Florida, haveinvented certain new and useful Improvements in WindowPane Fasteners,and I do hereby declare the following to be a full, clear, and exactdescription of the 1 invention, such as will enable others skilled inthe art to which it appertains to make and use the same.

This invention relates to window sashes and more particularly to theformation of the glass-holding rabbet the object of the invention beinto provide a positive lock for holding the glass and putty in placewhile at the same time insuring proper position of the glass while theputty is being put in place.

I am aware that it has been proposed to form in the sash a grooveextending under the edge of the glass so that the putty when ut in placewill in part enter this groove and 'e against the edge of the glass andbe held thereby against removal.

In such structure, however, I am not aware that any means have beenprovided for holding the glass properly centered during the applicationof the putty.

the

In the accompanying drawings, Figure 1 is a sectional view taken throughthe stile of a window sash constructed in accordance with my invention.Fig. 2 is an edge view thereof before the application of the putty, and,Fig. 3 is a view similar to Fig. 1 showing a slight modification of theinvention.

Referring now to the drawings, and more particularly to'Figs. 1 and 2thereof, there 'is shown a stile 5 of a window sash, in the inner edgeface of which is formed the usual rabbet havingthe walls 7 and 8 atright-angles to each other, and against the wall 7 is received the paneof glass 10. The rabbet results in ormation of a bead 6 having the wall7 in common withthe rabbet. In the wall 8 of the rabbet is formed agroove 9 a slight distance from the wall 7, which'results in ashoulder'15. The shoulder 15 extends all,

the way around the opening in the sash that receives the glass, so thatwhen the glass is put in place agamstthe wall 7, its edge lies againstthe shoulder 15 and the glass is thusglass projects part way over thegroove 9 and thus partially closes entrance to the groove. The putty 11is disposed against the face or wall 8 of the rabbet and against theouter face of the glass 10 as is usual, but in pressing the putty intoposition, it is forced into the V oove 9 which it completely fills, sothat it ies against the edge of the glass 10. Now the breadth of thegroove 9 is greater than that of the uncovered portion of the o ening sothat the groove is in effect inwar ly enlarged when the glass is inplace. Thus a positive lock for the putty is formed.

I am aware that it has been proposed to form the groove 9 at the base ofthe wall 7 of the rabbet, so that the inner wall 16 of the groove willbe in the same plane as and in effect be a continuation of t e wall 7 ofthe rabbet. In such a construction, however,

care must be taken that the glass does not move into contact with thebottom of the groove in a stile or in the communicating grooves of twoadjacent stiles and thus prevent pro er locking of the putty against theedge of t e glass. In the present construction, the shoulder 15accurately centers the glass and absolutely revents it from movingagainst the bottom of any of the grooves 9 in the stiles. Thus theinwardly enlarged effect of the groove is positively assured and a mosteflicient locking of the putty is obtained.

In the form of the invention shown in Fig. 3, there is provided a secondgroove 12 s aced a slight distance from the groove 9 an paralleltherewith, and into which the putty may also enter to further lock it.

This case forms a continuation of my prior application, Serial #362,158,filed March 13, 1907, and subsequently formally abandoned by me.

' What is claimed, is,

1. The combination with a Window sash adapted to receive a glass, saidsash having a bead arranged to receive one face of the glass and havinga putty-receiving groove in its inner edge spaced from the bead adistance sufficient to form a shoulder, of a pane of glass disposedagainst the bead with its edge against the shoulder, the thickness ofthe glass being greater than the width of the shoulder whereby the glassprojects from the shoulder and part way over the groove, and a body ofputty disposed against the sash and that face of the glass opposite tothe bead, said putty entering the groove and lying against the exposededge of the glass.

2. A window sash formed with a rabbet and a resultant bead, the sidewall of which rabbet has a groove whose outer Wall is spaced from thebeada distance greater than the thickness of the glass, a portion of thesash between the bead and the outer Wall of said groove being disposedto engage the in her portion only of the edge of the glass with theremainder of the edge of the glass exposed in the direction of thebottom of the groove, the side wall of the rabbet beyond the outer wallof said groove lying sufficiently far above the bottom of the groove tocooperate vith the exposed edge of the glass in forming a positive lockfor putty disposed in said groove.

sear-2e glass having the inner portion only of its edge resting uponsaid receiving portion, and the remainder of its edge exposed in thedirection of the bottom of the groove, and a body of putty disposedagainst the face of the glass opposite to the bead, the putty enteringsaid groove and lying against the exposed edge of the glass.

4. A. Window sash formed with a rabbet and a resultant bead, the sidewall of which rabbet has a groove whose outer wall is spaced from thehead a distance greater than the thickness of the glass, a portion ofthe sash between the bead and the outer wall of the groove beingdisposed to engage the inner portion only of the edge of the glass withthe remainder of the edge of the glass exposed in the direction of thebottom of the groove, the side wall of the rabbet beyond the outer wallof said groove lying in the plane of the edge of the glass.
